Nathan Morton and William True Jr., along with Michael McNaughton, are facing charges in connection with the death last month of Romeo Parent, 20.

AUBURN, Maine (AP) _ Maine authorities have charged two more men in connection with the death of a man believed by one of the alleged assailants to be a police informant.

Nathan Morton was arraigned Thursday on conspiracy and murder charges along with 23-year-old Michael McNaughton, who was charged last month and faced a bail hearing in the death of 20-year-old Romeo Parent. Also arraigned Thursday was William True Jr., who's charged hindering apprehension or prosecution.

Police believe Parent was killed late on April 9. His body was found three days later in a stream.

The Sun Journal says police believe Parent and McNaughton were friends but that McNaughton had come to believe Parent had served as an informant on criminal matters.
